写一个 Python 程序，在偶数位置甚至索引位置打印列表项。在这个 Python 偶数位置示例中，列表切片从 1 开始，在列表末尾结束，并递增 2。
evList = [3, 6, 9, 11, 13, 15, 17, 19]
print('Printing the List Items at Even Position')
print(evList[1:len(evList):2])Python 程序使用 for 循环在偶数索引位置打印列表项。
evList = [17, 24, 36, 48, 55, 79, 82, 93]
print('Printing the List Items at Even Position')
for i in range(1, len(evList), 2):
print(evList[i], end = ' ')Printing the List Items at Even Position
24 48 79 93 Python 程序，使用 while 循环在偶数位置打印列表项
evList = [90, 120, 240, 180, 80, 60]
print('Printing the List Items at Even Position')
i = 1
while i < len(evList):
print(evList[i], end = ' ')
i = i + 2Printing the List Items at Even Position
120 180 60 在这个 Python 示例中，for 循环从 0 迭代到列表长度。if 条件检查索引位置除以二等于 1。如果为真，则打印偶数位置列表项。
evlist = []
evListTot = int(input("Total List Items to enter = "))
for i in range(1, evListTot + 1):
evListvalue = int(input("Please enter the %d List Item = " %i))
evlist.append(evListvalue)
print('\nPrinting the List Items at Even Position')
for i in range(1, len(evlist), 2):
print(evlist[i], end = ' ')
print('\nPrinting the List Items at Even Position')
for i in range(len(evlist)):
if i % 2 != 0:
print(evlist[i], end = ' ')Total List Items to enter = 8
Please enter the 1 List Item = 12
Please enter the 2 List Item = 23
Please enter the 3 List Item = 34
Please enter the 4 List Item = 45
Please enter the 5 List Item = 56
Please enter the 6 List Item = 67
Please enter the 7 List Item = 78
Please enter the 8 List Item = 89
